Image acquisition apparatus and data recording method

Abstract

According to one embodiment, an image acquisition apparatus includes a removable recording medium which is attached to a recording medium requiring certain time for starting up, and configured to record data when only a system program is started, an image processing unit which generates an image signal to be recorded, a switching control unit which causes the attached recording medium to record an image signal generated by the image processing unit during startup of the attached recording medium, wherein information can be recorded in a short time after a main power supply is turned on.

1 . An image acquisition apparatus comprising: 
 a main recording medium capable of recording data, which requires certain time to be started up to a data recordable state;    a recording medium which is configured to record data when only a system program is started, and attached to the main recording medium;    an image processing unit which generates an image signal; and    a recording medium switching unit which causes the attached recording medium to record the image signal generated by the image processing unit during startup of the main recording medium.    
   
   
       2 . The image acquisition apparatus according to  claim 1 , wherein the recording medium switching unit has a signal input unit to instruct switching of the recording medium.  
   
   
       3 . The image acquisition apparatus according to  claim 2 , wherein the attached recording medium switched by the signal input unit is a RAM, and the image signal recorded in the RAM is moved to the main recording medium when the startup of the main recording medium is finished.  
   
   
       4 . The image acquisition apparatus according to  claim 2 , wherein the attached recording medium switched by the signal input unit is a removable semiconductor memory, and the image signal recorded in the semiconductor memory is moved to the main recording medium when the startup of the main recording medium is finished.  
   
   
       5 . The image acquisition apparatus according to  claim 1 , further comprising an image display unit which is configured to display the image signal generated by the image processing unit when only the system program is started even during the startup of the main recording medium.  
   
   
       6 . The image acquisition apparatus according to  claim 5 , further comprising a signal input unit which instructs the recording medium switching unit to switch the recording medium.  
   
   
       7 . The image acquisition apparatus according to  claim 6 , wherein the attached recording medium switched by the signal input unit is a RAM, and the image signal recorded in the RAM is moved to the main recording medium when the startup of the main recording medium is finished.  
   
   
       8 . The image acquisition apparatus according to  claim 6 , wherein the attached recording medium switched by the signal input unit is a removable semiconductor memory, and the image signal recorded in the semiconductor memory is moved to the main recording medium when the startup of the main recording medium is finished.  
   
   
       9 . An image acquisition apparatus comprising: 
 a lens which takes information to be recorded;    an image signal generation unit which generates a signal corresponding to the information taken by the lens;    a main recording medium which has a large capacity though requiring time for starting up, and records an image signal generated by the image signal generation unit;    a recording medium which is configured to record the image signal when only a system program is started, and attached to the main recording medium;    a display unit which displays an image corresponding to the image signal generated by the image signal generation unit;    an image display control unit which processes the image signal to be displayable and supplies to the display unit; and    a recording medium switching unit which causes the attached recording medium to record the image signal generated by the image processing unit during startup of the main recording medium.    
   
   
       10 . The image acquisition apparatus according to  claim 9 , wherein the recording medium switching unit causes the display unit to display an image corresponding to the image signal.  
   
   
       11 . A data recording method comprising: 
 starting a system program when a main power supply is turned on;    recording data in a first recording medium configured to record data, when the system program is started;    transferring the data recorded in the first recording medium to a second recording medium, when startup of the second recording medium requiring certain time for starting up to a data recordable state is finished; and    recording subsequently supplied data in the recording medium.
